I walk relatively slowly - around 3.5km/h on average - as I'm still recovering from a broken hip injury (damn SPD wouldn't open). I have Fenix 6X Sapphire, and set it to walking or hiking, depending on whether I use trekking poles or not. After my activity I get cadence readings in Garmin Connect up to 195, which is - to put it mildly - absurd! What gives???
